Traumatic cardiac arrest
Choose a channel above the diaphragm (intravenous infusion vs bone marrow aspiration);
Consider a management transfusion protocol (MTP);
Consider thoracotomy if necessary;
Initiate advanced cardiac life support (ACLS);
early intubation;
Left lateral decubitus position (LUD);
Peripartum cesarean section was performed 4 minutes after cardiac arrest;
Call the obstetrics and gynecology and neonatal intensive care teams.
Unstable state (loss of airway, GCS < 9, BP < 80/40, HR < 50 or > 140, FHR < 110 or > 160)
Airway: For early intubation, consider using a smaller endotracheal tube diameter (6-6.5 mm);
Breathing: Supplement oxygen, perform chest drainage if necessary;
Circulation: Establish intravenous access above the diaphragm, perform a transfusion management protocol (MTP) if necessary, place in the left lateral decubitus position (LUD), stop bleeding, and administer tranexamic acid (TXA);
Fast ultrasound (FAST);
Perform chest X-ray (CXR) and pelvic X-ray (PXR) when necessary;
If the fetus is viable, call the obstetrics and gynecology and neonatal intensive care teams;
Initiate fetal heart rate monitoring (EFM): If fetal heart rate monitoring is level III, perform emergency cesarean section;
Laboratory testing: complete blood count (CBC), coagulation function test, fibrinogen, blood group and cross-match, KB test if Rh negative;
Surgical intervention as needed;
Stable state (preliminary assessment shows no abnormality)
Conduct a secondary assessment;
Establish intravenous access above the diaphragm;
Laboratory tests: complete blood count (CBC), coagulation function test, fibrinogen, blood group and cross-match, and KB test if Rh negative;
Imaging examination: fast ultrasound (FAST), bedside fetal ultrasound, X-ray and CT scan if necessary (target dose <5 rad);
If Rh negative, give Rh immune globulin (Rhogam);
Perform a pelvic examination if necessary;
Start fetal heart rate monitoring (EFM);
Routine fetal ultrasound;
Monitor for 4 hours
minor trauma;
No physical examination findings;
Fetal heart rate monitoring is reassuring;
Less than 1 contraction every 10 minutes;
Monitoring for more than 24 hours
major trauma;
Physical examination findings: uterine/abdominal tenderness, vaginal bleeding, rupture of amniotic fluid (ROM);
Having multiple contractions every 10 minutes;
Fetal heart rate monitoring results are not reassuring (category II);
Fibrinogen < 200;
emergency caesarean section
Fetal distress, manifested by grade III fetal heart rate monitoring results
Uterine rupture
Placental abruption with significant bleeding
Fetal malposition accompanied by premature birth
